China has been blamed for the change in colour

Arunachal Pradesh made headlines when reports of its Siang river turning black garnered mass attention. WION previously reported on the growing distress among the locals in Arunachal Pradesh and a mass appeal -- led by Ninong Ering, Congress MP from the east Constituency -- urging the central government to take immediate action.

Arunachal Pradesh Chief Minister Pema Khandu has also intervened and sought help. According to an ANI report, Khandu has urged the centre to take immediate action on the worsening state of Siang river.

"I have personally monitored the condition of Siang river. Yes, it is a matter of concern and the water is badly polluted. The water pollution has damaged the marine life. I have also asked the Deputy Commissioners of the state to submit a report on it soon," ANI quoted Khandu. The Chief Minister has also forwarded his petition to the central government.

Siang, a constituent river of the Brahmaputra, starts its course from Tibet -- where it is called the Yarlung Tsangpo -- and travels down to Arunachal Pradesh from where it flows to Assam and comes to be known as the Brahmaputra. It flows from a 1,600 kilometre stretch in southern Tibet before entering India.
